If they only would take the time to explain things simply you would understand.

This is an interesting one. I field this comment quite often from undergraduates, and it’s hard to carve out enough quiet space in a conversation to explain what they’re doing wrong. In a way the proliferation of math on YouTube might be exacerbating this hard step from tourist to troubadour.

You might reconstruct your sacred Jeffries prior with a more refined notion of model identity, which incorporates derivatives (jets on the geometric/statistical side and more of the algorithm behind the model on the logical side).
